A NEW END-TO-END FAILOVER MECHANISM WITH TRANSPORT LAYER MULTIHOMING
Jiemin Liu, Shaohui Cheng, Yuhui Zhao, Yuan Gao · 2007
Using the application of bulk data transfer, we investigate current end-to-end temporary failover mechanism, permanent failover mechanism and relative threshold's design for transport protocols that support multihoming (e.g., SCTP) again. We find that they have a common defect, both of them neglect idle-multipath's initiative utilization when they are interested in fault tolerance and failover. Both mechanisms increases the possibility of global failover synchronization. Based on this, we first present a new approach to end-to-end failover mechanism (i.e., Circular Failover mechanism based on three-level threshold). Such a mechanism further improved failover's performance by a new threshold design, realized idle-multipath's initiative utilization and logical traffic balancing by the other new threshold design. We demonstrate that such a mechanism can further improve failover mechanism's comprehensive performance than existing well-known failover mechanism.
